Icon's meaning in the "Scroll Lookup Words"-window of the Still OCR

[dxcarnadi]

Hello

I've a tablet Nexus7 (2013) Android Version 4.4.4.
I've bought the Pleco Profi-bundle and now I'm playing in the "Scroll Lookup Words"-window of the Still OCR.
On the right side of the tablet (landscape) there are 12 icons in 2 rows .. without hint-keyword.
I know only a few (f.e. loudspeaker).
Where in the Pleco's online manuals can I read about those icons?
I didn't find them.
Thank you.
